Experimenting and Getting Caught

I was at my friend's house with 2 other girls (my friend and another) and 3 guys. This happened about a month ago. We were just hanging around and talking and then we started playing truth or dare. Then one of the guys dared my friend Jackie to kiss one of the other guys. So it turned sexual.

Jackie was a really daring person and she went over and started kissing a guy named John. Then Jackie dared another guy (Mike) to flash his dick at us. But Mike, who was also daring, more than flashed his dick... He actually pulled down his pants for like 30 seconds and started dancing around, and just as he was putting his pants back on we could see that he was getting a boner. Then it was Mike's turn and he dared me to choose someone to feel my tits. To make a long story short and move onto the masturbation part of the story, the truth and dare game got really sexual and after about 10 minutes all of the girls were in their bras and panties and the guys had no clothes on but their underwear.

It was Jackie's turn to dare someone and she dared Mike to pick a girl to go over to Mike, (we were on the floor), pull down his boxers, sit on his lap, and start grinding up against him. Mike chose Jackie and they started doing this. They kept going at it for like 3 minutes and then Mike stuck his hand inside Jackie's panties and started fingering her. And then Jackie started jacking Mike off, and so they were masturbating each other.

Then the other girl who was there (most of whose stories I left out) started rubbing the other guy's dick (whose truth/dare stories I did not tell) and soon they were masturbating themselves- Jackie and Mike were the only ones who were actually masturbating each other. This all happened within another few minutes.

Then John came over to me, stuck his hand down my panties, and started massaging my clit. I rubbed his cock through his boxers but didn't take them off yet. After a minute or so I took off John's boxers and he took off my panties. I started jerking him off but he told me to hold on a second. Then, while everyone else was masturbating or masturbating each other, John said that him and I should do a different way of masturbating. So I said OK, what way? He said I should lay down and that he should be on his knees so that he could try thrusting his dick back and forth on my pussy without going inside it, and he said he would finger me while doing this. I thought this was sort of dumb but I said ok. We did it and he started off fingering me and I was jerking his dick. Then he took his dick and rubbed it around my pussy... Not going inside at all but thrusting back and forth flush with my skin, when he realized that he was not going to reach an orgasm by doing this. So I had him lay on the ground, and while I jerked him off he had his fingers in my pussy and we masturbated each other.

This is the masturbation focus of the story. John and I both had an orgasm by him fingering me and me jacking him off and so did the other girl and guy whose names I didn't say...
